SHUTTLE FOR LOOMS.

Specification of Letters Patent.

Patented Get. 15, 1918.

To all whom it may concern:

Be it known that I, ALBERT B. WE1ssEN- BORN, a citizen of the United States, and resident of Appleton, in the county of Outagamie and State of Wisconsin, have invented new and useful Improvements in Shuttles for Looms, of which the following is a descrip tion, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a shuttle particularly designed for use with wire weaving looms for weaving wire cloth, such as Fourdrinier wire, but capable of more general use, and having as its distinctive feature of construction rigidly positioned conical supporting rollers on which it travels, the conical shape thereof serving to give the shuttle a bias in the direction of the reed in either direction of travel thereof, thus causing the shuttle to hug the reed in its travel through the shed and avoid a detour from its regular path which might cause serious injury to the product.

Another object of the invention is to eliminate all tendency of the shuttle to skid or slide on the smooth surface of the shuttle board between the box and the beginning of the warp at the commencement of its travel. Such a tendency is particularly noticeable with wide looms where the shuttle has to be thrown with sufficient: force to carry it a great distance. This object is accomplished by forming the rollers of soft rubber which not only gives the shuttle perfect traction, but avoids injury to the warp wires in traveling over them.

With the above and other objects in view the invention consists in the shuttle for looms as herein claimed and all equivalents.

Referring to the accompanying drawing, in which like characters of reference indicate the same parts in the different views,

Figure 1 is a bottom view of a shuttle constructed in accordance with this invention; and,

Fig. 2 is a transverse sectional view thereof through the center of one of the rollers.

In these drawings 10 indicates the shuttle body which is provided with a cavity 11 in its bottom surface at each end thereof. Frusto conical rollers 12 of soft rubber are rotatably mounted in these recesses and form supports for the shuttle. Each roller I is fixed on an axle pin 13, the conical ends of which have a working fit in sockets in the ends of bearing screws 14 threaded through the walls of the cavity on an incline corresponding with the inclination of the axis of the roller, for the roller is tilted to make its line of bearing parallel with the bottom of the shuttle. The smaller ends of both conical rollers 12 are on the inclined or reed side of the shuttle which gives the shuttle a tendency to deviate from its straight line travel in the direction of the reed. Of course it-is prevented by the reed from departing from its straight line travel, but this tendency assures against its traveling away from the reed which is an important matter inasmuch as serious injury may be done to the fabric in case the shuttle leaves the reed.

In this manner I now accomplish by fixed tapering rollers the results forming the object of the inventions covered by my Letters Patent No. 1,015,524, dated January 23, 1912, and No. 1,119,182, dated December 1, 1914, and the absence of means for shifting the position of the rollers constitutes an important advantage.

The rollers being formed of soft rubber obtain a perfect traction upon the smooth polished surface of the shuttle board so that there is no sliding or skidding thereon and at the same time they do not injure the warp wires in traveling over them. lhe soft rubber yielding surface of the rollers furthermore assures contact at both ends thereof notwithstanding the slippage that is required by reason of the conical form, and thus the tendency to hug the reed is greater than it would be with rollers having a hard surface.

lVhat I claim as new and desire to secure by Letters Patent is:

1. A shuttle mounted on tapering rollers which have their axes parallel and inclined to the horizontal to give the shuttle a tendency to travel close to the reed.

2. A shuttle mounted on tapering rollers which have their axes parallel and inclined to the horizontal and fixed in position.

8. A shuttle mounted on conical rollers with their bearing lines parallel with the bottom of the shuttle and at right angles to the axis of the shuttle.

4 A shuttle having recesses in its bottom surface, inclined bearing screws threaded through the Walls of the recesses and having sockets on their inner ends, and conical rollers Within the recesses with trunnions journaled in the sockets of the bearing screws.

5. A shuttle mounted on conical rubber rollers Which have their axes parallel and inclined to the horizontal and their smaller ends next to the reed side of the shuttle.

6. A shuttle having recesses in its bottom surface, inclined bearing screws threaded through the Walls of the recesses With sockets in their ends, axle pinshaving conical ends fitting in the sockets of the bearing screws, and conical rubber rollers fixed on the axle pins.

7. A shuttle mounted on tapering rollers which have their axes parallel and inclined to the horizontal and have soft rubber yielding bearing surfaces.

In testimony whereof, I aflix my signature in presence of tWo Witnesses.
